Abstract

In this study, biodegradable polycaprolactone (PCL) nanofibers were copper (Cu) electroplated in a more environmentally friendly bath compared to conventional electroplating baths. The Cu-plating mechanism and determination of the optimum parameters for the production of Cu-plated PCL nanofiber mats were explained. PCL nanofibers were produced on metal frames by electrospinning. Cu-electroplating needs a conductive surface. To provide this, a gold/palladium mixing was sputtered on the PCL samples with different sputtering thicknesses. After determining the minimum sputtering thickness, the samples were Cu-plated for 1,3,5 and 30 minutes in the electroplating bath. Surface properties of the samples were evaluated after nanofiber production, Au/Pd sputtering and electroplating, respectively. Elemental analyses, mapping and electrical characterizations were also performed after electroplating. The Cu-coated areas gave a sheet resistance in the range of milliohms indicating a highly conductive structure. Every step of the study is described in detail to provide insight for further studies.

可生物降解PCL纳米纤维垫的镀铜

在这项研究中，可生物降解的聚己内酯(PCL)纳米纤维在一个更环保的镀液中电镀铜(Cu)，与传统的电镀镀液相比。阐述了镀铜机理及制备镀铜PCL纳米纤维垫的最佳工艺参数的确定。采用静电纺丝的方法在金属骨架上制备了PCL纳米纤维。镀铜需要导电表面。为此，在不同溅射厚度的PCL样品上溅射了金/钯混合物。确定最小溅射厚度后，分别在电镀槽中镀铜1分钟、3分钟、5分钟和30分钟。分别对制备纳米纤维、Au/Pd溅射和电镀后样品的表面性能进行了评价。电镀后还进行了元素分析、绘图和电学表征。铜涂层区域的片电阻在毫欧姆范围内，表明具有高导电性结构。研究的每一步都被详细描述，为进一步的研究提供见解。
